Application filed April 15, 1922. Serial No. 552,934.

To all whom-"it may concern:-

Be it konwn that I, VICTOR H. PALM, a-

the pumping-valves, but in lieu thereof to use fluid for raising and lowering the pumping valves or pistons, thereby doing away with the cumbersome mechanism heretofore and is discharged out of the outer tube.

employed and thegreat power required to operate same.

To accomplish the above object I employ two strings of tubes one-inside the other, so arranged that when full of fluid the pressure will'beon opposite sides of a. plunger to which the working-plunger and valve is attached. When both tubes-are full of fluid the pressure against the said plunger is nearly balanced except for the area that the valved plunger displaces.' By puttingextra pressure alternately into the tubes by means of a pump that discharges through a timingvalve it is so arranged that when one tube is receiving more pressure the other will beex'hausting,iso that the plunger and.

the valved plunger connected thereto is reciprocated up and down. The fluid from the' well is pumped out on the down'stroke,

The timin valve is geared to the engine or motor, an fast the motor runs, the size of the pressure pump, v and how, fast the' well is to be pumped. t

In the accompanying drawings, Fig. 1 is a side elevation of the pump and engine and the connection to the well; Fig, 2 is a ver tical sectional view ot the upper portion of the pump in the well; Fig.3 is a like view of the lower portion of the pump; Fig. 4 is a section on the (line 14, Fig. 2; and Fig. 5 shows the detailed connection between the inner tube and the working-valve.

In the drawings the numeral 2 designates a suitable pressure-pump connected up to the cross-head. 3 of a suitable steam engine or the ratio is determined by how motor A. I do not, however, limit myself to a pump 2 connected up in this way to the-engine, as it may be geared or beltdriven, or may be operated by a'separate engine or motor. A suitable pressure-gage 4 is provided, and a safety-valve 5 regulates thenpressure that is put in the tubes in the we the ordinary steam chest ofa steam engine withits ports 8 and 9 controlled by the ordinary D-valve 7 without any overlap,

A chest 6 is provided which is similar to said valve controlling the ports 8 and 9 connecting with the tubes 10 and 11 leading into the well,

The valve? is connected up by the rod 12 to the eccentric 13, said eccentric being mounted on the vertical shaft 14 which has the worm-gear 15 meshing with the worm 16 on the engine shaft.- In this way the timing-valve is geared to the engine and the ratio is determined by how fast the engineor' motor runs, the size of the pressure-pump and how fast the well is to be pumped.

The exhaust-port .17 delivers the fluid from the pipes 10 and 11 back into the tank 18. The valve 19 controls the fluid to the pump, so that there will be the right amount for the displacementof the plunger in the well for the distribution valve 7. 1

A stufling-box 20 is provided to pack the tube 11 where it enters the tube 10 in passing down into the well. The tube 10 is supported from the top of the well and carries the ump and working barrels.

The tu ing 11 also hangs from the top of the well and is connected to the tube 21 which extends through the stufling-bdx 22 at the upper end of the barrel 23. The tube 21 has the pins or lugs 24 which are, adapted to engage the recesses 25 formed in the gland 26 of the stufling-box 22 when it is desired to turn the gland 26 totighten the packing 27..

The tube 21 is square in cross-section as at 28 after it passes through the stufling- 'box 22, and. said square portion passes through a like opening 29 in the head 30 of the plunger 31, which is adapted to move .up and 'down in the barrel 23,

The square portion 28 of the tube 21 is provided. with the perforations 32 so that the fluid can enter the hollow plunger 31 and work on the inner face of the lower head 33 thereof, as well as the upper end.

The upper end of the plunger 31 is provided with the pins 34 which are adapted-to engage the recesses formed in the gland 36, so that by brin ing said pins into engagement with saic .reeesses the gland 36 may be turned to tighten the packing 37.

he plunger 31 is connected at its lower end to the tube 38 which has perforations 39 which bring said tube into communication with the chamber 40 with the perform tions 41 leading into the space 42 between the barrel 23 and the outer barrel 43, so that the fluid coming up through the tube 38 can pass out into said space 42 and out through the pipe 10.

The tube 38 has the pins or projections 44 which are adapted to engage recesses 45 of the gland 47, so that by turning said tube the gland is lowered and the packing 48 tightened.

Connected to the lower end of the tube 38 is a working-valve 49 of the ordinary construction having the cage 50 with the ball valve 51 normally resting on the seat 52. This working "alve is adapted to move up and down in the barrel 53 which is com nected by thecollar 54 to the stuffing-box 47. The collar 54 is provided with the perforations 55 to permit anyfluid leaking past thevalve 49 or stufling-box 47 to es cape.

The numeral 56 designates the customary anchor or perforated pipe at the bottom of the well, and above the same in the barrel 53 is the ordinary standing-valve 57. A coil spring 58 is interposed between the standing-valve 57 and the working-valve 50, said spring acting to keep the pins 34 and 44 from striking their respective stuffing-box glands when the fluid is used to force the lunger down. When it, is de sired to tighten the different glands the tube 11 is disconnected at the top of the well and then lowered until the pins engage in the several glands. The seats or recesscs formed in the several glands vary in depth so that when the tubing 11 is lowered the upper pins will engage the top gland, and by lowering the tubing still 1 farther the lower glands will be engaged,

'- so that if it.-is found that the first packing is tight it can be looseneda little and then tightened with the next one lower down. In order to efl'ect the engagement of the pins with the several glands it will be necessary 'to compress the spring 58. A casing head 60 of the ordinary construction is em: ployed to permit of the drawing ofi of gas.

When in operation the pump 2 will act to alternately deliver fluid to the pipes 10 and 11. When fluid is delivered under pressure to the pipe 11 the said 'fluid passes through the perforations in'the lower endoisaid tube into the plunger 31, and said fluid acting on the inner bottom face of said plunger and on the upper end of said passes up through the working valve 50 and pipe 38 and is forced out through the openings 41 into the space 42 and thence into the pipe 10 which is connected up to the exhaust 17 connected to the tank. The slide-valvc 7 then operates to direct the fluid under pressure into the pipe 10, the pipe 11 being connected up to the exhaust, whereupon the fluid passes down through the space 42 through opening 41 into the chamber 40 to act on the lower face of the plunger 31 to lift: the same, As the plunger 31 moves upward the standing-valve 57 is opened and fluid is admitted to the lower end of the working-lmrrel 53 below the working-valve 51, and this fluid is again lifted by the lowering of the plunger 31, as previously described.
